  • BenQ BlueCoreTM Laser Technology Laser Technology for Pure Color
  • Precision-Aligned High-Output Laser SourceZero-deviation alignment of BlueCore laser diodes boost luminous flux into the light tunnel, improving light efficacy to 3,600 lumens.
  • Secondary Yellow-Infused Color WheelDual synchronized BlueCore color wheels utilize an additive yellow segment, stimulating precise RGBY spectra for optimal chromatic performance.
  • Hermetically Sealed DLP ChipComprising over two million micromirrors that reflect pure light through the color wheel, the DLP chip is hermetically sealed to resist heat for over 100,000 hours without degradation.
  • Superior Dustproofing Design to Prolong Projector Lifespan
  • Sealed Engine for Laser Light Source
  • Anti-Dust Accumulation Sensor Resists Dust Buildup
  • LW820ST’s powerful BlueCoreTM laser projection utilizes a dual color wheel system to produce outstanding color performance by increasing color ratios and purity of RGBY colors, greatly enhancing color saturation and brilliancy at the same lumen output of lamp-based projectors to deliver superior viewing experiences.
  • LW820ST produces 3,600 ANSI lumens and superior brightness efficiency, at the same level as IFPs for clear, sharp images and text even in large, bright classrooms with lights kept on during lessons.
